I am having the same problem.
I try to set the server as indicated on
I can go and change the server as indicated
but when I try to save
Invalid Incoming Mail Server
The “Incoming Mail Server” field cannot be empty.
The incoming mail server is there, but it is grey and I can't change it.
So, is there any way to change the outgoing server so I don't have to select one every time I send an email?
